whats up cgm new to the site i was wondering if i can get some advice on a 5.3 to lq9 swap i got a 2000 gmc sierra
what would i need to change and also will there have to be any changes to the cpu?any tips on what else to do? thanks for the help
 
Welcome.

Direct swap,truck will run fine on the 5.3 tune,but to optimize the swap you really need a good tune afterwards.
Change the rear main seal before you swap it in, depending on mileage maybe some new lifters and trays for cheap insurance.
 
thanks i appreciate it also
comp cam 331/339 cam
comp hardened push rods
brian tooley double valve springs
65lb injectors
msd wires
high flow long tube headers
motor has 800miles
mototr puts 500hp to the ground
also have built 4l60 trans
 
I think your a little off on the cam specs.. Ive never seen a ls cam that big.
No need for 65lb injectors,you dont need over 35-36#.
Motor is not putting 500hp to ground.
 
Like Ginger said, build the trans and rear to hold the power before you do the nitrous. Both will grenade very soon. And definitely find a good tuner, you'll blow your shit up so fast it's not even funny with nitrous if it's not done right
 
just throw a 400 shot at and see what happens i am sure it will be fine ....make sure you get a video
 
^this. Nos sucks, just run all motor or boost it

Just went back and re-read your cam specs, where the hell did you get those? Not any came I've ever heard of.
65lbs injectors are definitely wayyy too big
Ain't no way it's making 500 at the ground, with that much cam and injector it's drowning itself
 
"650hp+ with 3200 stall sold seperate" :lolwut:

Someone message this bafoon 661-401-0685
And tell him he's a bafoon
 
Cam must also be super top secret ultra custom grind.
Because the only 2 google results that come up with that cam spec is that CL ad, and this thread :rofl:
